COMBINED DOOR LATCH AND STOP.

SPECIFICATION forming part of Letters Patent No. 597,219, dated January 1 1, 1898. Application filed J'uue 28,1897. Serial No. 642,687. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE D. PETTINGELL, a citizen of the United States, residing at J efferson, in the county of Green and State of Iowa, have invented certain new and useful Improvements in a Combined DoorLatch and Stop, of which the following is a specification.

My invention relates to that class of doorfasteners which consist of two arms adapted to connect the door with the casing in such manner that the door may be opened slightly to inspect any doubtful character on the outside, for ventilating, and for other purposes, and yet prevented from being opened surficiently to allow a person to enter without first disengaging the said links, which action cannot be effected from the outside when the door is partly opened, but which may be readily done when the door is closed to permit the door to be entirely opened in the ordinary manner.

The object of my invention is to provide a simple, strong, secure,and inexpensive device for the purpose stated and also to provide in connection with said door-securing arms a sliding bolt, which will serve to fasten the door when closed, as will hereinafter appear.

My invention consists in certain constructions, combinations, and arrangements of parts hereinafter particularly described and claimed with reference to the accompanying drawings, in which Figure 1 is a perspective view illustrating portions of a door and door-casing'with the door open to the full limit of the check-arms with my improved device in its operative position; Fig. 2, a front elevation of portions of the door and easing with the door closedwvith my device in position thereon and with the sliding bolt locked; Fig. 3, a horizontal section in line was of Fig. 2 with the door opened, as shown in Fig. l; and Fig. 4, a horiiontal section in detail through the sliding bolt, the barrel, and the sleeve and shoulder of the check-arm supported in said barrel.

The door-casing A and door B are of the ordinary construction, the door being hung to admit of its opening inwardly.

A barrel-plate O is secured by wood-screws c to the casing A and consists of two barrelsections 0 and 0 the outer section 0 being of larger diameter to receive both the sleeve d of a coupling-arm D and also formed with a transverse slot 0 therein from a point near the top fastening-plate to a point at the junction of the barrel with the bottom fastening-plate c of the said barrel to admit of the oscillation of the shoulder of said couplingarm D from a horizontal position (shown in Figs. land 3) to a depending vertical position, (shown in Fig. 2 of the drawings) but to hold the said sleeve securely and prevent it from being moved longitudinally Within the barrel. The barrelsection 0 receives a sliding bolt E, having a knob e, the neck of which passes through an H-shaped slot in the said barrel-section c and is thus supported and adapted to be reciprocated longitudinally in the sleeve (Z of the coupling-arm and be secured in one of the cross-notches in a withdrawn position, as shown in Figs. 1, 3, and 4, or secured in a projected position to engage with the door.

The door is provided with a coupling-arm F, extending at right angles from a sleeve f, which latter is secured to the door B by a barrel-plate G, which has an upper fasteningplate g, extending the full length of the barrel, and a lower fastening-plate 9, extending part way of the length of the barrel and secured to the door by wood-screws 9 a slot 9 being provided upon the under side and outer end of the said barrel to allow the coupling-arm F to slide back to the position shown by dotted lines in Fig. 2 whenv it is required to release the coupling-arm D from the coupling-arm F and thus allow the door to be opened. The coupling-arm D has an eye d at its end and the coupling-arm F has a laterally-projecting pintle f at its end, which engages with the said eye to form a hinged connection therewith, and a pin f projecting from the coupling-arm F, provides convenient means for reciprocating the said arm and its sleeve f when the pintle f is to be disengaged from the eye cl of the coupling-arm D and thus allow the door to be fully opened. A stop-lug f on the sleeve f prevents the said sleeve from being withdrawn from the barrel-plate G and thus disconnected from the door. The outer end of the sleeve fat the shoulder of coupling-arm F provides a socket or staple for the end of the sliding bolt E, as shown by dotted lines in Fig. 2,

although this is not necessary. The sliding bolt may be of suflicient length to fit into the sleeve f either when the latter is in its outer or when in its inner position.

In operation the bolt E is first withdrawn from the door by moving it from the position shown in Fig. 2 to the position shown in Fig. 1, and the door may then be opened until the coupling-arms are both extended their full length in a direct line, as shown in Figs. 1 and 3, a further opening of the door being then impossible. As the sleeve of the coupling-arm D cannot be moved longitudinally in its barrel at any time and as the couplingarm F cannot be moved to withdraw its pintle f from the eye (Z of the coupling-arm D after the said arm 1) has passed the edge of the door, it will be impossible to disconnect the coupling-arms from each other when the said door has been opened or moved the least bit away from the casing. Persons from the outside cannot therefore open the door without completely destroying the fastening. When the door is closed, the bolt may be moved to engage with the sleeve of the coupling-arm F or to cross the eye of the door and secured in this position, thus bolting and holding the door securely in its closed position. After the bolt is drawn back, as shown in Figs. 1, 3, and 4, the coupling-ar1n is moved to the position shown by dotted lines, Fig. 2, to disengage the pintle f from the barrel of the coupling-arm F, thus allowing the door to be opened freely to the fullest extent.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A door-fastener comprising two sleevesections each having a link-arm projecting therefrom adapted to be engaged with or disengaged from each other, and barrel-fastenings to receive the said sleeves and allow them to oscillate and one of them to slide within said fastenings, substantially as described.

2. A combined slide-bolt and door-fastener comprising two sleeve-sections one to interlock with the other, each having arms to engage at their ends one with the' other, fastening-plates adapted to hold said bolt-sections and allow them to oscillate in said plates, and a slide-bolt held to slide in one of said sleevesections, substantially as described.

3. In a check-bolt or door-fastening, the combination with the door and easing of a coupling-arm and sleeve thereon, a barrelto receive the sleeve of the second couplingarm and allow it to oscillate and also to move endwise therein to adapt it to be coupled to or uncoupled from its connecting-arm, sub stantially as described.

4. In a check-bolt or door fastening, the combination with the door and easing of a two-part coupling-arm, each section comprising an arm and sleeve,an eye formed upon one of said arms and a pin formed upon the other arm to engage one with the other, and barrelfastenin gs adapted to receive the said sleeves and admit of the oscillation of the arms and also of their lateral movementto disconnect one from the other, substantially as described.

5. A check-bolt or door-fastening comprising a two-part coupling-arm, each arm-section thereof having a sleeve and a barrelfastening adapted to allow said arms to oscillate one of said barrel-fastenings allowing its sleeve to move longitudinally therein to disengage its arm from connection with the conneeting-arm, substantially as described.

6. A check-bolt or door-fastening comprising a two-part coupling-arm adapted to engage one with the other, each arm-section having a sleeve and a barrel-fastening, one of said sleeves being adapted to move longitudinally in its fastening and having a lug to project therefrom to prevent its withdrawal from said fastening, substantially as described. V

7. A check-bolt or door-fastening comprising a two-part coupling-arm, each arm-section having a sleeve and a barrel-fastening, one of said sleeves being adapted to move longitudinally within its fastening to be disengaged from the connecting-arm section, and a bolt adapted to slide within one of said sleeves and projecting across the edge of the door to fasten the same, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in the presence of two subscribing witnesses.

GEORGE D. PETTINGELL.
